Overall it was good, but the flight was long and crews on such long flights in my experience generally get more involved. They make more rounds with water and snacks and check on wellbeing of passengers. It was not an overnight flight, so the ‘night’ atmosphere in the cabin was not called for

Overall it was good, but the flight was long and crews on such long flights in my experience generally get more involved. They make more rounds with water and snacks and check on wellbeing of passengers. It was not an overnight flight, so the ‘night’ atmosphere in the cabin was not called for

Overnight flight in the old style Business class, but still very good.

I was in business class, without the business class amenities. Large seat with lots of legroom, but no TV or bed. Food was okay, but I did enjoy the Turkish red wine.

This aircraft is not up to standard - old Airbus with terrible chairs and entertainment system for business class!

Friendly cabin crew and the flight was on time. Would recommend toanyone

The seat did not recline and we called the stewardess, he forced it to recline, but when we landed, it did not come forward because the seat was broken. The stewardess came, He tried to do it but couldn't do it, the flight commander came and spoke to us in a bad tone, telling us to get out of here, she waited at the head and acted as if there was a child and we couldn't get up, it was very shameful, I don't even know if it's true, but she said if you don't get up, the plane will not land and will keep turning around. Then a passenger pushed the seat from behind and it worked. Then we wanted to talk to the supervisor again, but she did not come next to us. We fly so much and this is the first time we encountered such a style.

Excellent service and comfort from the moment you check in. Flight crew is hyper focused on making passengers comfortable and at ease. It’s like a flying hotel!

Horrible. Boarding was terrible. For a huge airplane, we needed to be transported to the plane. The boarding area was overcrowded and frantic. .The seats were so uncomfortable. The food was fine.

Only chicken as a meat dish through out the flight

Nothing really was great as such. Seen other no name airlines perform better.

Pegasus is not a very comfortable airline. They’re not in any way hospitable

It was like moving cattle around. Very abrupt, uncomfortable and not much hospitality

All good but air not give the pasing er any food even glase of water

Flight delayed by 1hr when we already boarded because someone had to get off. Leg room is terrible for 6ft people like me.

I used the airline 5-6 times for the last year and every flight have had perfect timing and I like it. Despite catastrophic absence of space for my legs 😁

The crew was utterly non helping and non courteous.I asked for a water. The air hostess could have said it's paid . She informed me that I will come later after serving but never turned up. The seats were never comfortable.My first and last flight with Pegasus.I am not taking again

The plane left Istanbul 1 hour late and the AC was not really working great it was so hot inside and no air. This was my worst flight in a long time since I had a flight with Ryanair.

Cheap and cheerful. It’s a super cheap, no frills flight. Very professional and as it’s an A320 relatively spacious. Seats do not recline. Happy with the service. You get what you pay for. Can’t complain

I had 4 flights for less than a week and there were no delays and issues. Thanks to the crews and for perfectly organised service.

There is no usb for charging the phone you should provide the water
